试验结果表明，高压水射流粉碎过的煤泥浮选后其精煤的灰分含量为煤泥直接浮选精煤含量的一半，全硫含量仅为煤泥直接浮选精煤含量的五分之一。
The results of the flotation experiments shows that the ash content of the washed coal is only half of the coal slurry flotation without comminution by high pressure water jet, and the total sulfur.
试验还考察了油浆灰分含量对过滤结果的影响及反洗处理后过滤器初始压力降的恢复情况，为生产性过滤装置的设计提供了试验依据。
Rational filter processing parameters were obtained. The influence of ash contents on filtration and resumption of initial pressure drop of the filter after blowing back were also investigated.
